PETROG includes patent protected technology.
PETROG has a wide range of supported input formats. It will allow you to import single photographic image, a set of photographs that comprise a mosaic of a sample or a whole slide image from a slide scanner.
You can also use PETROG to scan a slide and provide an image which you can then analyse at a later time >>
Scanned images
Below is an image from a poster presented by Dr Ricki Walker in 2025 which shows the workflow of scanned images, interpreation and how PETROG fits into the workflow >>
